The problem with game AI is that they "cheat". They don't play like a human. The civ AI straight up gets extra resources, AlphaStar in SC2 performed inhuman feats like giving commands in two different areas of the map simultaneously or spiking actions per minute to inhuman levels briefly. But even with all of that the AI still eventually loses. And then they start losing consistently as players play more against them.

Why? Because AI doesn't learn on the fly. The AI does things a certain way and beating it becomes a puzzle game. It doesn't feel like playing against a human opponent (although AlphaStar in SC2 probably came pretty close).

Learning on the fly is probably the biggest thing that (game) AI is lacking in. I'm not sure there's an easy solution for it.
